Specification of Letters Patent. Patented Dec, 27, 1921.

Application filed August 23, 1919. Serial No. 319,307.,

To all whom it may concern: I

Be it known that we, Fnnonnron i /Ellison and HARRY F. SI-IINDL'L, bothcitizens of the United States, residing at Reading, in the county ofBerks and State of Pennsylvania, have invented certain new and useful Tmprovements in Goggles, of which the following is a specification.

This invention relates to eye protectors; and it consists in theimproved construction hereinafter set forth in connection withtheaccompanying drawing, and the novel ieatures or" which are fullydescribed, and specifically defined in the claims.

Figure 1' is an inner face view of complete. eye protector embodying theseveral features oi the invention in preferred form; one of the pivotedeye shields beingrepre sented in outwardly-swung operative position, andthe other one, together with the pivoted temple indicated, being shownin folded position.

Fig. 2 is a correspon the left hand clamping c ip and its attached headconnection being disconnected and shown separately in Fig. 3. f

Fig. 1 is an outside-edge view of the split lens lamping framing, as itappears preliminary to inserting the lens; the latter being shownseparately in Fig. 5 in connection with an edge-reinforcing ring. Theeye shield is indicated in raised position.

Fig. 6 is a similar view to Fig. i, but showing the framingpreliminarily closed upon the inserted lens, and so held by the fullyswung eye shield.

Fig. 7 shows the separateiy formed framing end-pieces.

Fig. 8 is an enlarged View of a portion of the lens framing, inconnection with, a showing of the clamping clip as about to be engagedwith thetraming end pieces; Fig. 9 being a similar view showing thefully engaged clip, in vertical section.

Figs. 10 and 11 are vertical views of 1e clip and of the nose-bridge endportion r-' spectively.

Each lens framing, as shown, is formed or" folded sheet material, with aions-edge engaging portion 10, and a circular eye cup or flangeextension 11; and is provided with end-piece members 12, 12 adapted tobe clamped together for securing the inserted members.

ng top-edge view lens 13. The eye shield 15, pivoted to the lens framingextension 11 at 16, 16, has its curved base portion 17 formed with acircular groovelS which is adapted to engage the top-edge portion of theframing exten sion 11 when the shield is swung outward to its operativeposition; the shield, when thus engaged, holding the abutting end piecemembers 12, 12 together so as to retain the previously inserted. lensand permit the easy applicationoi' the spring-clip 20 to said This clipis attached to the usual temple or head band connection 21 and isadapted to clampingly engage the end piece members 12, 12 in a mannersimilar to that shown in Vfillson Patent No. 1,323,431 of Dec. 2, 1919,but with improved efiect as hereinafter fully described. V

The end-piece members 12, 12, as shown in Fig 7, are separately formed,with flange portions 22 for rigidly securing them to the abutting endsof the split lens framing; and they consist of abuttingly arrangedplates, the lower portions of which are formed with clip-fulcrumingoffsets 25 on their inner edges, and the upper portions withtit-engaging recesses 28 to provide frictional enagement with thefullyengaged clip. The atter, as shown particularly in Figs. 8,19,

blank; its spaced-apart walls providinga flared opening 27 between themfor the easy passage of the abutted end piece members 12, 12, and beingconnected by a bottom and 10, is formed from a tolded'sheet metalcross-bar 28 which is adapted to engage the f fulcruming offset 25 ofsaid members. Ex

tending portions 80, 30 of the clip walls form a temple bar connectingjaw, and inwardly projected tits 31 of the clip walls are arranged tofrictionally engage the recesses 26 of the end-piece members after theful-y crumed clip has been forced into fully engagged position upon saidmembers.

The circular extension 11 of the framing, which forms a shallow eye cupportionand serves, as already described, for connection of the pivotedeye shield, and for clampingly edge inwardly turned, to conform itapproxiengaging the latter when in outswung' posi' base of the nose.

mately with the spreading sides and rounded The nose bridge connectionof the framings consists of a shaped bridge bar, having T-shaped endsformed by separate plates 85; the raised intermediate portion of each ofsaid plates being shaped to firmly seat the turned end of the bridgebar, which is rigidly secured thereto, and the ends of the plates beingshaped to the curvature of the framing extension 11 and suitablyfastened to the latter so as to provide any determined spread of' thelens framings.

In assembling the parts,or in removing and replacing the lens, theivoted shield operates in connection with the detachable spring clip togreatly facilitate the clamping operation. The shield itself is adaptedto hold the spli' framing together, upon the readily inserted lens; andit enables the spring clip, which completes the clamping, and firmlysecures the temple or head securing means, to be easily appliedorremoved; While the improved clip construction provides a convenientfulcrum upon which the device is swung with proper leverage for securingthe final frictional engagement. The special shaping of the eye cupframing eX- tension to which the eye shield is pivoted, adapts thelatter to serve as a preliminary lens-clamping means and at the sametime provides a symmetrical nose-contact and for the improvednose-bridge attachment,

What we claim is 1. in an eye protector, a lens-clamping framing havingopposed end-piece members and an eye-cup extension, a detachably enga'ed spring-clip band for the abntted members, anda pivoted eye shieldadapted to hold said members together without interfering with theoperation of said band.

2. In an eye protector, a lens-clamping framing having opposed end-piecemembers With clip-fnlcrurning offset, and a detachably engagespring-clip encircling said members and having an offset-engagingcrossbar.

3. In an eye protector, a lens-clamping framing having opposed end-piecemembers with clip-fuleruming offset, and a detachably engagedspring-clip encircling said members and having an offset-engagingcrossbar adj acent one end of its opening and a friction catch adj acentthe other end thereof.

a. in an eye protector, a lens-clamping framing having opposed end-piecemembers with clip-fulcrumed offset, and a detachably engaged spring-clipencircling said members and having an offset-engaging crossbar adj acentone end of its opening, a friction catch adjacent the other end thereof,and a templeconnecting jaw.

In an eye protector, a lens-clamping framing iaving opposed end-piecemembers with clip-fulcrumed ofiset, and a detachably engaged spring-clipencircling said members and having an offset-engaging crossbar and atemple-connecting jawadjacent one end of its opening, and a frictioncatch adjacent the other end thereof.

6. In an eye protector, a lens-clamping framing having opposed end-piecemembers with clip-fulcruming offset, and a detachably engagedspring-clip encircling said members and having an offset engagingcrossbar; the encircling portion of said clip having a flared openingfor passage of the engaged end-piece members.

7. In an eye protector, a pair of lens framings each having an eye-cupextension, and a nose bridge bar having rigid T-shaped curved endportions extending circumferentially of the respective cups and rigidlysecured to the latter.

In testimony whereof we aliin our signatures.
